Function om_decoder_next_index_read 

pub unsafe extern "C" fn om_decoder_next_index_read(
    decoder: *const OmDecoder_t,
    index_read: *mut OmDecoder_indexRead_t,
) -> bool

@brief Determines the next range of chunks to be read and updates the om_decoder_index_read_t structure.

This function calculates the next set of chunk indices that need to be read from the data, based on the limits set by the maximum I/O size, alignment, and the logical structure of the data. It updates the om_decoder_index_read_t structure to reflect the new range of chunks and the corresponding read parameters.

@param decoder A pointer to a constant om_decoder_t structure containing information about the data array, chunk sizes, I/O constraints, and other relevant parameters. @param index_read A pointer to an om_decoder_index_read_t structure, which will be updated with the next range of chunks to read and the corresponding offset and size of the read operation.

@returns true if the next read range was successfully computed and updated in index_read. false if there are no more chunks left to read, indicating that the end of the read range has been reached.
